SETTING THE DRAFT (6500 Furnace)
A proper draft setting is crucial to the successful burning of solid fuels. Draft refers to the amount of air
flowing through the burn chamber of your stove. Too much or too little draft will cause your furnace to
burn improperly and may result in the fire burning out. Please follow these guidelines carefully as you
operate your furnace to achieve maximum efficiency and value..
 The amount of draft required for your furnace to burn properly will depend upon your installation and
the fuel you use. You can set your draft by looking at the flame and following these guidelines. The
manual draft lever is the rod and knob on the back right side of the unit. Turning the lever toward a
vertical position increases the draft and turning the lever toward a horizontal position decreases the
draft. A little movement of the lever goes a long way to changing the flame. It may take several trial
and error adjustments on the draft to achieve the correct setting.
 The flame should be an "active" flame. A flame that moves around lazily and emits visible smoke
needs more draft. To give the fire more draft, turn the lever counter-clockwise 1/8" and check the
flame again. If the status of the flame has not changed, move the lever another 1/8" until you get a
clean "dancing" flame. If moving the damper does not change the fire, you might have negative
pressure in the home. Consult with your Magnum installer.
 The base of the flame should be blue in color and the top of the flame should be yellow.
 If the flame does not have enough draft, fuel will build up in the firepot and eventually smother the
flame. If this happens, or if you notice the firepot is filling up with partially burned fuel, open the
damper 1/8" at a time until the fire is clean and dancing.
 If the flame has too much draft, the flame will look like a torch in that it will be moving rapidly and
blowing fuel out of the firepot. If you find that you have this condition, move the damper counter
clockwise 1/8" at a time until the condition of the flame changes.
When you change fuel sources it may become necessary to readjust the damper control knob. You should not have
to continually adjust the manual knob except when using the high fuel setting. The circuit board automatically
adjusts the air to the firepot on the settings from 1 to 3.
